rare white gems or decadent side stones

[Marlow]

I love rare gems and esp. the sometimes extremely rare colorless varieties.

Left: three colorless (and eyeclean) Taaffeite ( 0,09 - 0,13 ct) // a rare colorless 0,12 ct Benitoite // two 0,10 and 0,11 ct Leucogrossular



The 3 Taaffeite with a 0,74 ct Taaffeite ( has a slight color shift)

They're so little What's the smallest stone you own? The leuco grossular garnets particularly grab my interest.

A tiny little canadian Eudialyte facetted - the vendor offered four stones so I took them all - think it is 1 or 2 points.

Yes, they are completely colorless - I posted larger Leucos here but they have often a hint of yellow, green or brown.

Neat to see Marlow! Shouldn't the small size help the leuco's to stay colorless, as there's less gem material for light to travel through? I've been looking for a pure leuco over 1ct., but I am beginning to believe by the time they get to that size they *all* show some tint...

I can't see any color in indirect daylight. Of course they are very small.

I have a 0,91 ct and 1,64 ct round which are colorless in incandescent light and faceup in daylight - from the side they have a tiny hint of
color ( yellow) - would be interesting to check them with a masterset.

If you expect an D-G like a diamond I would say it is impossible to find in a 1 ct size.

May stones are from eastafrica - they show a pink LW fluorescense - burmese material is included / never seen eyeclean stones.

Left the two larger round - at the end a Merelani Mint to compare...



Please look at the girdle - in the tip ( Merelani too ) you see a reflection of my hand
